The direct system is calculated with the formula N = (W/l) / (L/w). The indirect system uses the formula: N = (L/w) / (W/l). In these formulas, N is the yarn count, W is the weight of a sample of yarn, l is the unit of length, L is the length of the sample, and w is the unit of weight.
How do you determine yarn count?
Yarn count refers to the thickness of a yarn and is determined by its mass per unit length. It is usually measured by the number of grams per one kilometer of yarn, a unit of measure called “Tex”.
How do you calculate yarn count in GSM?

How does yarn count affect the fabric?
Figure 5 depicts the effect of yarn count and stitch length on fabric width in tubular form at different processing stages. It is clearly evident from the figure 5 that with the increasing of the yarn count and stitch length, the fabric width was decreased in dyeing and washing state and finished state.
How is cotton count calculated?
As you can see, Cotton Count is the length by weight, and Tex and Denier are the weight by length.
3 Common Thread Terms
- Cotton Count (NeC): The number of 840 yard lengths of material in one pound.
- Tex: The weight in grams of 1,000 meters of thread.
- Denier: The weight in grams of 9,000 meters of thread.
Which yarn count is finer?
The count of yarn expresses the number of length units in one weight unit. Thus higher the count, finer the yarn. The system is generally used for cotton, worsted, linen (wet spun), etc. Where, W = The weight of the sample.
What is the difference between yarn count and thread count?
Yarn count is the number of threads per square inch within a fabric. Directly affecting the yarn count is how fine or wide the yarn fiber is within the fabric. Larger fibers in diameter take up more space, so will have a smaller thread count.
What is GSM count?
GSM (also known as gm/2) = grams per square meter and is the metric measurement of the weight of a fabric.
Is GSM the same as thread count?
How is GSM different to thread count? Strictly speaking there’s no comparison to be made between GSM and thread count. One measures the weight of a fabric, while the other the number of single threads woven to make that fabric.
What is warp count?
The number of warp yarns per one inch or centimeter of fabric. This is also called sley, warp end count, ends per inch, or ends per centimeter.
Why is yarn selection so important for knit fabric production?
It is important to observe that production of staple yarn is not limited to composition from one kind of fibre the staple of two or more kinds of fibres may be combined for blended at different stages. When different types of fibres are blended, the properties of these fibres are also combined in the blended yarns.
Why is yarn count important?
Count of yarn is important to produce specific quality of yarn. … It also expresses weather the yarn is thick or thin. A definition of yarn is given by textile institute “Count is a number indicating the mass per unit length or the length per unit mass of yarn”.
What is yarn count system?
In textiles, yarn count is a number that represents the diameter or fineness of a yarn, either in terms of weight by length or length by weight. … The indirect system measures the length of a consistent weight of yarn, with a higher yarn count indicating a finer yarn.
What is the yarn count of cotton?
Cotton Count is defined as the number of 840 yards length of yarns in one pound. It means that the number of yarns of 840 yards length required weighing one pound. For example, a 30 count yarn means you need 30 yarns of 840 yards length to make it one pound weight.
Which count of cotton yarn is finest?
On 25 October 2008 finest yarn (350 Ne/ 592 Nm) ever spun 100% cotton has been produced on Pilot Spinning Mill, Spinning Research Department, Cotton Research Institute. Also, the old one, 334 Ne or 565 Nm was recorded by Messrs, TEXParts in Stuttgart, Germany.
What is count cotton?
Technically, the ‘thread count’ is the number of threads woven together in one square inch of fabric, counting the threads both horizontally and vertically. The idea is that the more threads you count, the more luxurious the sheet.
